wired: use 802.1X-2001 instead of 802.1X-2004
For wired authentication the protocol version used in the EAPOL
packets sent by ead is fixed to 802.1X-2004 (2) but some switches
implementing only 802.1X-2001 erroneously ignore these packets.
As ead only sends EAPOL-Start and EAP-Packet packets and these have
not changed between 802.1X-2001 and 802.1X-2004 there should be
no reason to use 802.1X-2004. Hence, this changes ead to always use
802.1X-2001 (1) instead.
Switches implementing newer versions of 802.1X should not have
problems responding to packets using the original version.
